Well, in modern digital recording virtually all music involves looping, digital overdubs, and more production work than a Hollywood film. Not that this didn't happen before, it was just more difficult. There's a lot that goes on behind those studio doors that no one knows because it ruins the magic. I appreciate all types of music, and have enjoyed recording all types for the last 10 years. From a production standpoint, the routes are orchestra, fits destiny/star wars style. The female vocal/choir/a Capella version of a popular song I.e. evolves live trailer with the fugees - ready or not. Awesome track, check it out. -games always do well in this tone Or Edm/dub step/trap extremely high energy, spacey, different, futuristic - fits the vibe of our future-ish post apocalyptic setting. On to making dub step, trap, or any edm really. There many be some goofy soft synth that has premade wobbles or something like that. Even these fruity loop producers can't punch a dub step track together, at least not a respectable one. Something like abelton has the ability to loop, for percussion tracks or whatever, but if your not a jag off you could easily play the whole song from a midi controller record it. Then the track is laid out in audio/midi and through various commands altering pitch etc. And possibly looping at this point, the Crazy wobbles are born. It could take hours of tinkering to make a single sound. Its easily abused by amateurs, but I can't rank them with all dub step artists. A hammer and saw can be used to build a house, so can power tools. It's when people expect those power tools to build the house for them, that we have garbage results.
